SUCTION APPARATUS.

To all whom it may concern:

Be it known that I, ADELBERT SAUER, a citizen of the United States, anda resident of Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented a new and Improved Suction Apparatus, ofwhich the following is a t'ull, true, and exact description.

The object of the invention is to provide a new and improved suction orvacuum apparatus, for heating, ventilating, refrigerat ing and otherpurposes.

Forthe purpose mentioned use is made of a suction chamber provided withan annular passage connected with a steam supplyand from which lead anumber of spiral passages into the suction chamber to produce a vortexblast in the suction chamber.

A practical embodiment of'the invention 'is represented in theaccompanying drawings forming a part of this specification, in

which similar characters of reference indi-- cate corresponding parts inboth views.

Figure 1 is a sectional side elevation of the suction apparatus, thesection being on the line 1--1 of Fig. 2; and Fig. 2 is a cross sectionof the same on the line 2-2 of Fig. 1.

Within a suitably constructed'shell A are arranged twooppositely-disposed suction devices B and B having suction chambers B2B,preferably of conical shape, with the apex ends toward each other, asplainly indicated in Fig; 1. In the walls of the suction chambers B andB are formed annular supply. From the annular passages B, B lead spiralpassages B, BTinto the space A formed in the shell A between theapexends of the suction devices B and B. An outlet A leads from the space A,to carry off the steam and the air or other fluid drawn into the space A.by the suction devices B' and B. I

When the device is to be used for ventilat- 'ing purposes, for instance,use is made of pipes D extending through the ends of the shell A toterminate in the base ends of the suction-chambers B and B the outerends a of the said pipes D being connected to rooms Specification ofLetters Patent.

annular passages B, B and the spiral passages B, B into the space A. Itis evident that. by the production of this vortex blast,

a suction is produced in the chambers B, B

and consequently a suction takes place in the pipes D;to .draw ii: thefoul air from the room or other place to be ventilated, and this foulair commingling with thesteamis diss charged through the outlet A to aplace of discharge. The pipes D are supported in the shell A by crossplates E, as plainly indicated in Fig. 1.

Whenit is desired to use the apparatus for heating and other purposes,use is-made of a circulating 'pipe F extending lengthwise in the'shelland passing through the suction chambers B B when the pipe is heated bythe steam.

.It is understood that when the apparatus is used for ventilatingpurposes, the v foul air drawn into the space A commingles with thesteam and the mixture passes out of the outlet A to a'suitable place ofdischarge or is conducted to other machinery or apparatus to be used asmotive power, etc.

In using the apparatus for heating purposes steam is caused to circulatethrough the circulating pipe F to heat the air drawn in by the suctiondevices B, B through the air sup ly pipes -D. For refrigeratingpurposes,t 1e liquid to be cooled is caused to circulate through the pipe F andair is passed into the apparatus under a high velocity by way of thepipes D and through the suction action of the steam in the chambersB BThe air in this passage through the chambers 13 B comes in contact withthe circulating pipe F and thus cools the same and the liquid flowingthrough the same.

In using the apparatus for the manufacture of artificial. ice use ismade ofshallow trays containing water and fluid'in' the suction chambersB, B, so that the inrushing air traveling at a high velocity passes overthe water and freezes the same.

The apparatus may be used as, a steam condenser, and in this caseexhaust steam is conducted through the pipe F, and the velocitiy oftheinrushing air by wayof the pipes and passing over the pipe F cools thesame and causes the steam to condense.

Although I have described a few uses of the apparatus, it is evidentthat I do not limit myself to such use, as the apparatus may be used forother purposes.

so v

,and extending from the said annular pas- Having thus described myinvention, I claim as new and desire to secure by Letters Patent:

1. An apparatus of the class described, comprising a shell, a pair ofconical suction chambers arranged in the shell. and having their apexends opposite each other and spaced apart, each of the suction chambersbeing provided in its Wall at the base end with an annular passage, andspiral passages formed in the Wall of the suction chamber sage to theapex end of the suction chamber, a steam pipe connected with the annularpassages of the said suction chambers, an outlet leading from the saidshell at a point between the apex ends of the said suction chambers, andpipes extending through the en'dsof the shell and terminating'in thebase J ends of the said suction chambers.

2. Anapparatus of the class described, compr]sln gallell, a .pairofconical suction chambers arranged in the shell and having their apexends opposite each other and spaced apart, each of the suction chambersbeing provided in its wall at the base end with an annular passage andspiral passages formed in the wallet the suction chamber and extendingfrom the said annular passage to the apex end of the suction chamber, asteam pipe connected with the annular passages of the said suctionchambers, an

outlet leading from the said shell at a point between the apex ends ofthe said suction chambers, and a circulating pipe extending in the saidshell and passing through the said conical suction chambers.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
